a. The digital signals that are shaded gray are the power-on default values for the corresponding GPIO pin.
8.2 Functional Description
Each GPIO port is a separate hardware instantiation of the same physical block (see Figure
8-1 on page 406 and Figure 8-2 on page 407). The LM3S5D91 microcontroller contains nine ports
and thus nine of these physical GPIO blocks. Note that not all pins may be implemented on every
block. Some GPIO pins can function as I/O signals for the on-chip peripheral modules. For information
on which GPIO pins are used for alternate hardware functions, refer to Table 23-5 on page 1206.
